FLUE-LEAK INVERTOR.

To all whom it may concern Be 1t known that I, LEVY E. CARTER, a c1t1-ville, in the county of Madison and Stateof Alabama, have invented newand useful Improvements in Flue-Leak Invertors, of

- Which the following is aspecification.

This invention relates to means for temporarily stopping leaks intubular boilers.

The object of the present invention is to provide a means for coveringthe water leaking from around the flue of a defective boiler, anddelivering it to said flue thereby preventing it from reaching the firebox.

Another object of the invention is to provide a device for insertion inthe fine of'a locomotive boiler, which may be applied at any time,irrespective of the fact that fire may be at the time within the firebox.

A further object is the provision of a device of this class forinsertion in the flue of a boiler, and held securely therein by directcontact with the inner Wall of the flue.

"With the above objects in view the invention consists of a tubularmember provided with longitudinal open ended slots, a circumferentiallygrooved flange formed upon one end of said member and communicatingtherewith, an enlargement formed upon the outer surface of thetubularmember and an abutment provided in the end of said member. 1

In the drawings;

Figure 1 is an elevation of theend of the locomotive boiler, showing'theflue sheet, and having the invention applied to one of the tines;

Fig. 2 is an enlarged longitudinal section through the end of one of thefines, with the invention in position;

Fig. 3 is a similar view taken at right angles with Fig. 2 and on theline 22 thereof.

Fig. 4 is a detailed perspective view of the invertor removed;

Fig. 5 is a view similar to Fig. 2 illustrating a modification of theinvention;

Fig. 6 is a detailed perspective of this modification removed from theflue; and

Fig. 7 is a detailed perspective of the invertor and the holder utilizedfor inserting it in the flue.

In the practical form of my invention, the same consists of a tubularmember 1 pro- Vided with oppositely arranged longitudi- Specification ofLetters Patent.

nal open ended slots 2, in order to provide a. resilient end and permitthe compression and expansion of the member. Formed upon the oppositeend of the tubular member is a flange 3, having formed in its rear facea circumferential groove 4 adapted to communicate with the interior ofthetubular member" byvmeans of oppositely arranged openings 5. The frontand rear walls of the openings 5 are inclined for the purpose of morereadily directing the water from the groove 4 into the interior of thetubular member 1. Formed around the inner edge of the flange 3 is acircular groove 6, provided with an asbestos or other packing 7, s0 thatwhen the device is in position it will form a leak proof joint betweenthe flue sheet and this edge of the flange.

To further aid in securing the device within the flue, which is shown at9, the tubular member is provided intermediate its ends with anenlargement 10, sloping toward the rear end of the member 1 in order toprovide for the easy insertion of this member within the flue. In theevent of a leak occurring around the flue, the device is inserted untilthe packing 8 is seated firmly against the flue sheet, so that the leakfrom around theflue will enter the groove 4, and pass into the tubularmember through the openings 5. At the end of the tubular member isformed an abutment, which in the preferred form of the inventionconsists of a circular flange 11, which effectually prevents the leakingwater from dripping out of this end of the flue into the tire box, thedraft through the said flue aiding to carry the water in the oppositedirection.

In the modified form of the invention the end of the tubular member isentirely closed as shown at 12, so that there is no possibility of thefire or cinders stopping up the flue, otherwise action of the inventionbeing the same. 7

In order to permit the device to be inserted into the flue'while thereis fire in the fire box there is provided a holder 13, having formedupon one end a seat l-l adapted to receive the flange 10 of theinvertor, so that the same may be inserted in the end of the boilerflue, and the operator remain at some distance from the flue sheet.

From the foregoing description it will be seen that theinventionproxddes a quick and eflicient means for preventing. the waterfrom around a leaky flue reaching the fire box, and directing itbackward through the said fiue away from the fire.

Having described the invention, What is claimed, is: a

1. The combination with a boiler, of a tubular member, said tubularmember being :municating with the interior of the tubular member throughopeningsprovided in said member adjacent the flanged end thereof.

Iiopies of this patent may he obtained for "2. The combination With aboiler, of a tubular member, said member being longitudinally slottedatone end in a manner to permit of the same being compressed for in'serti'on Within a boiler flue and a circumferentially grooved flangeformed at the opposite end of said member cooperatmg with the tace ofthe boiler to provide a closed annular chamber, said chambercommunieating with the interior of the tubular member through "openingsprovided in said member adjacent the flanged end of the same,

the tubular member being further provided at :utsflanged end with anannular inwardly extending Wall.

In testimony whereof I my signature.
